How much mA does a NiMH cell need to charge?
The original NiMh cells are very easy to charge if you charge them slowly. Which is the case as your charger only delivers 200mA. When a NiMh cells is full, at 200 mA it will just get a bit warm and that's OK (not ideal, just OK).
Why are NiMH cells used in vacuum cleaners?
Reasons why: The NiMh cells are very likely high current cells, meaning they are designed to be able to deliver the high current that a vacuum cleaner motor needs . If you use "standard" Li-Ion cells these will not be suitable for such high currents so even if they do work they will wear out quickly.
What type of clamp is used for precision voltage control?
If you want a precision-bodge-job you could provide an eg TL431 + pass transistor clamp per cell to allow precision voltage control. Which is what I intend to try.
Can you charge a vacuum cleaner with 4 cells?
Using 4 cells you could charge to 16V (if the charger allowed it) and probably not harm the vacuum cleaner. This has a "flat" voltage of 4 x 3V = 12V. Or, you could use 3 cells and clamp to 12V. This would provide 9V when cells were fully exhausted at 3V cell - stopping at a higher voltage prolongs cell life.
Can you replace dead cells with new cells?
You're better off replacing the dead cells with new, same model, NiMh cells or just buying a new vacuum cleaner.
Can Li-ion cells be charged?
Li-Ion cells cannot be charged with a continuous 200 mA, charging MUST stop when the cells are full. If charging does not stop you risk damaging the cells maybe they overheat and could start smoking or catching fire. As you will need some Li-Ion cells in series to make the voltage required, the charger needs some balancing circuit as well. That's complex and expensive.
